Kadife Kırmızı Gül ve Sarmaşık Gül Boyası ile Duyarlılaştırılan Boya Duyarlı Güneş Pillerinin Fotoelektrik Dönüşüm Verimlerinin Karşılaştırılması
Bu çalışmada, kadife kırmızı gül ve sarmaşık gül bitkisinden elde edilen özütler, boya duyarlı güneş pillerinde duyarlılaştırıcı olarak kullanıldı. XRD analizleri, TiO2 ince filmin anataz yapısını doğruladı. SEM fotoğrafları, nanokürelerin birbirleriyle sıkı temas halinde olduğunu ve TiO2 yüzeyinde daha fazla boya emilimine izin verdiğini gösterdi. UV-vis analizinden, kadife kırmızı gül boyasının görünür bölgede daha geniş bir absorpsiyon sergilediği anlaşıldı. I-V karakterizasyonları incelendiğinde kadife kırmızı gül boyası ile duyarlı hale getirilen hücrenin sarmaşık gül boyası ile duyarlı hale getirilen hücre'ye göre daha yüksek hücre performansına (ɳ=0.12)sahip olduğu görüldü.

Comparison of Photoelectric Conversion Efficiencies of DSSCs Sensitized with Velvet Red Rose and Ivy Rose Dye
In this study, extracts from velvet red rose and ivy rose were used as sensitizers in dye-sensitized solar cells. XRD analyses confirmed the anatase structure of the TiO2 thin film. SEM photographs showed that the nanospheres were in tight contact with each other, allowing for greater dye absorption on the TiO2 surface. It was understood from the UV-vis analysis that the velvet red rose dye exhibited a wider absorption in the visible region. The I-V characterizations showed that cell sensitized with velvet red rose dye exhibited higher cell performance (ɳ=0.12) than DSSC sensitized with ivy rose dye.
